    Default DTI Engine Stutter

    Hi, was just taking a video of my car with it's new donor engine starting up. I started it up and it fired up ok, but then started to chug and misfire. Then it started running fine. Does any body know what caused this. I am thinking it could be a dodgey injector, or a timing issue. But as you'll see from the video it runs fine after the hicup !!

    Here's a link to the youtube video [URL="http://www.youtube.com/watch?v=7-9tslMyJnc"]http://www.youtube.com/watch?v=7-9tslMyJnc[/URL

    Engine 2.0 DTI Y20 DTH. New DMF flywheel and clutch fitted as well.



    Cheers...

    Take the crankshaft speed sensor out of your old engine if available and swap them over.

    Hi, this has already been swapped from my old engine, there was no ECU warning on the dash. Starting to think its sounds like the flywheel again !! If you listen to the engine tone it doesn't change, it's something else knocking....

    Honest mate check the crank shaft sensor, clean the magnetic end, clean the electrical contacts with WD40, check the wire hasnt snagged.

    what was the problem with your old engine ?

    The DMF failed on the old engine, this caused the crank to snap in the center. So I replaced engine with a donor engine, a new DMF, clutch, pressure plate & slave cylinder... I replaced all parts from my old engine on the the donor as this engine was sold as a bare engine.

    If the crank sensor was dodgey would it not flag up an error in the ECU and display a warning on the dash ?

    Cheers.

    Ok the snapped crank would most likely have killed the sensor it sits fractions of a millimeter from the toothed crank wheel.

    They tend to give a cam shaft speed sensor not present error once they are completely dead but the dti does not have a cam shaft speed sensor, I had a astra y20dth and the crank sensor didnt register a single error but once replaced the car ran a dream.
    Normaly ( Petrol engines) have crank and cam, they can run happy with 1 dead / disconnected sensor but as the DTI doesnt have a cam sensor it doesnt log the fault till the sensor is completely dead)

    Do you a deal you get a new sensor from Vaux if it doesnt fix the problem ill send you the cash for your lay out on it.

    I think this could of been the top(simplex) / lower (duplex) chain tensioners.

    The engine was very low on oil, so I guess the tensioners were not getting any oil and were not working correctly.

    It hasn't happened again.....

    is the video from the very first time u started it? if so it could have been a sticky valve or hydraulic lifter as the engine had been sitting for just over 8 months

    Hi mate, it had been run for about 20 minutes the previous day. So the engine had been used. The oil is pretty low, just on the end of the dipstick, and on reflection it was possibly this that caused the oil filled tensioners to not work as they should. I am doing an oil change very soon, possibly Sat morning, so if it happens again after that it must be something else.

    It has only happened once, and it was while I was recording it starting up, quite lucky to catch it doing it ... So it hasn't done this since then; but I have not been using the car that much anyways.


    Cheers...
